Rotating Header text overlay possible?

Hi all!

As I'm just returning to this forum after a long absense, 1st let me say how impressed I am with all the progress made on what was already a great theme!! Great job to all involved!

For a new project I'm working on, I need to have rotating text overlayed on the header image in the same way now possible for either the Blog Title and Tagline.

1) Ideally, I'd like to have a single text file with each text statement on a new line and just pull a random or ordered line of text every x seconds to overlay and refresh the header area time?

2) If not possible, is there a way to have individual text files with each text statement and cycle them in the same way presently done for the header image?

3) If this is not possible, can the header image be an animated gif with the text statement embeded into the gif file?

4) If all of the above is not possible, I guess the final fall back will be to create individual header images with each text statement overlayed, add them to the header image folder and let Atahaualpa do it's thing.
However, that's not ideal. Every time I need to add/modify a text statement, a new images have to be created and manually replace the old ones as needed

Thanks in advance for any ideas, suggestions or solutions you may have.
